Winter access is not maintained between Johnson and Mill Meadow reservoirs. Stream flows are much lower in the winter, so walk lightly and work on your stealth skills to avoid spooking fish. Low flow also often leads to surface ice, which can make fishing more difficult. Brown trout can get a little sluggish during the winter, but fishing can still be fair to good, especially on warm, sunny days. Access to the Fremont River above Mill Meadow Reservoir typically opens up in early-to-mid April. Fishing can be good in lower flows before water is released from Johnson Reservoir. Brown trout are abundant and can be caught on a variety of tackle.
